The Sawyer Mini is what I have, but with the dirty water bag and the back-flushing kit, tablets would take up less space.

It is a beautiful place; I've been once before, but I came from the East side and did the Buckeye - Caney Creek loop, so I never went as far as the river. I'm definitely keeping an eye out for ticks. Tomorrow, I'm going to treat our clothes with permethrin. Hopefully it's as miraculous as advertised.
